Application filed May 31, 1921. Serial No. 474,024.

To all whom it may concern Be it known that I, NIooLA A. Con'rnsn, asubject of the King of Italy, residin at Bovey, in the county of St.Louis and btate of Minnesota, have invented certain new and usefulImprovements in Railroad- Frogs, of which the following isa-specification, reference being had therein to the accompanyingdrawing.

This invention relates to railroad frogs and has special reference to aseparable frog, the parts of which may be taken out and renewed whenworn, the principal object of the invention being to provide a morepractical form of frog than at present known, and one which may beconveniently repaired and more readily handled than the one-piece solidfrog now in common use.

Other objects and advantages will appear in the further description ofthe invention.

Referring to the accompanying drawing forming part of this applicationin which like reference characters indicate like parts:

Figure l is a perspective view of one of the improved frogs, completelyassembled;

Fig. 2 is a reduced perspective view of the foundation portion of thefrog with the rail sections removed therefrom;

Fig. 3 is a perspective view of one of the angular rail sections whichis cooperatively engaged with the foundation section;

F ig. 4 is a similar view of one portion of the frogpoint;

Fig. 5 is a similar view of the other portion of the frog point;

Fig. 6 is a transverse section on the line 6-6, Fig. 1;

Fig. 7 is a transverse section on the line 7-7, Fig. 1;

Fig. 8 is a transverse section on the 1m 8-8, Fig. 1;

F ig. 9 is a transverse section on the line 99, Fig. 1.

1 represents the cast metal base or fundation of the frog, which, ingeneral, is of the usual shape employed for such purposes. Upon theupper face of the base and cast integral therewith is the centrallydisposed Y-shaped member 2 and the V-shaped member 3. Upon the ends ofthe bifurcated portion of the Y-shaped member are upwardly projectingenlargements 4 which form continuations of the heads of the angular orwing rail sections 5, when in position. The if-shaped member 2 iscut-away upon either side thereof as at 6 for the reception of tinprojecting base or flange of the rail sections when applied thereto andthe upper face of the base portion is chamfered or recessed for thereception of the base of the rails so that the rail sections whenproperly assembled in the base are virtually embedded therein andsuitable spikes may be employed for holding them in position.

The point of the frog comprises two pieces of rail sections 7 and 8, theformer carrying the entire portion of the extreme end of the point, asindicated at 9, the innermost extremity of which is notched as at 10 forthe cooperative reception of the chain fered end 11 of the portion 8 sothat when assembled within the frog foundation, one portion upon eitherside of the V-shaped member 3 they will unitedly form the completeswitch point. The upwardly projecting members 2 and 3 preferably extendupwardly approximately the height of the or dinary foot block so that inthis form of frog no foot block is necessary in providing safety asrequired.

I have shown a plurality of through bolts 12 which may be arranged asdesired for firmly uniting the various parts of the frog, and, ifnecessary, fish plates indicated at 13 may be employed. 7

From the foregoing it is evident that l have provided a form ofseparable frog, portions of which may be conveniently renewed orrepaired as desired, and one that may be readily taken apart fortransporting, or; the foundation of the frog made a permanent fixtureand the rail parts thereof repaired or renewed at will. the benefitsderived therefrom being obvious.

Having; thus described my invention, what I claim and desire to secureby Letters Patent, is: I

A separable frog of the character described comprising in combination abase separable parts of the frog, substantially as portion having aY-shaped upwardly exdescribed. 10
